Not there yet but thought i'd start early! :)

Hi and welcome - I'm not really sure what you're after and I'm not 'horsey' but I'll give it a shot at giving you some general information:

There's a riding school in Maghtab that we've passed frequently. There's another one near the Golden Bay Radisson resort.
You'll see horses and buggies everywhere outside the built-up or touristy areas.
Horse racing takes place at the horse racing circuit in Marsa.

At my workplace someone has a poster up for horse riding lessons - sounds like you're beyond learning though.

Not sure where you would be able to buy a horse though.

Be prepared, Horsemeat is on the menu at several restaurants.

Good luck
Tim

I've already heard about horsemeat being on the menu - aslong as i dont see them being slaughtered ill be ok....im not too squeamish!

Thanks for your info - still trawling the internet but looks like it will be one of those where i will have to wait until i am there to get some contacts etc

Don't know how I remembered this, but the main horsey place in Malta seems to be in Bidnija. There website is below, don't know if it's what you're looking for, but hope it helps.
